1. All springs may be backed o to 0 psig / 0 bar. However, highest capacities and best performances are obtained by using these springs in their recommended ranges.
2. Springs meet NACE MR0175-2002, NACE MR0103 and NACE MR0175/ISO 15156 requirements only for applications in which the spring is not exposed to the sour gas.
3. Available in Inconel
®
.
4. Spring range changes to 5 to 60 psig / 0.34 to 4.1 bar for the Inconel
®
option.
5. Spring range changes to 50 to 120 psig / 3.4 to 8.3 bar for the Inconel
®
option.
Inconel
